Trans athletes make great gains, yet resentment still flares

I'm fine with Bonds, Sosa, and McGuire going for records and I don't care what they took.
You should though. PEDs aren't allowed and they do enhance performance beyond what can be gained naturally or by other means. Either they're allowed and all the records are legit, or they're not allowed and some of those records aren't legit. Its really about having a fair playing field.
As far as COVID, masks are a completely different issue because wearing masks are about not physically harming others, not really about protecting yourself. It's about what you are putting in someone else's body, not your own body.

Second hand smoke also physically harms others so it has nothing to do with this.

What I pump in my body doesn't physically harm you and that's where I draw the line. If I cross that line based on what I put in my body there are criminal and civil penalties.
It harms those who compete without taking them. And the reason they don't take them is because it'sagainst the rules. I don't care if it's allowed or not, just make the rules the same for everyone. I'm not a fan of players breaking rules to gain an edge.
As far as the rest is concerned, my point is that having gendered divisions is just a product of women being thought of as lesser. There is no reason for them to not compete just like I, you, and every other male has to compete. Sometimes that means you reach a point where you aren't good enough, fast enough, or strong enough. And that happens whether you separate sports by gender or not. Which really means that competing with people of different genders is no more unfair than competing with people of the same gender that are just physically faster, stronger, and better.
